Abstract
The present invention discloses a maize parthenogenetic haploid-inducing gene ZmPLA1E and application thereof. The present invention utilizes the method of exchanged individual plant progeny tests for the first time, and successfully proves that the ZmPLA1E gene can generate and significantly increase the parthenogenetic haploid induction ability in the process of self-crossing or hybridizing as a male parent with other maize materials after the ZmPLA1E gene is mutated in the coding region. The haploid-inducing gene ZmPLA1E of the present invention is important for the cultivation of high-frequency parthenogenetic haploid inducing lines and the application of haploid technology.
